The structure and magnetic properties of Sm2Fe17 compound and its nitrides were investigated by means of differential thermal/thermogravimetric analysis.The result shows that the Curie temperature of Sm2Fe17Nx nitrides was improved obviously.The analysis shows that the increase of the Curie temperature was caused by interstitial N-atoms be incorporated into 3d-sublattice.At higher temperature than 700 K,the nitrogenized reaction of Sm2Fe17 became violent,in the meantime,the decomposed reaction of Sm2Fe17Nx took place and resultsed in SmN compounds and α-Fe.The Sm2Fe17 or Sm2Fe17Nx exhibited only single-phases of Th2Zn17 below 1473 K.
